c. Arabian race horse
d. Peppered Moth
e. Broccoli

Answer 1

Hint: Charles Darwin gave this concept of natural selection. This means those organisms will survive who will be selected by nature. Due to the limited amount of resources these concepts were proposed in which the organisms adapted themselves with the scenario.
Artificial selection is a process in which the breeder can choose the forms and enhance them in future generations. This process produces favourable offspring. This is implied to plants as well as animals.

Complete answer:
> Shetland pony was a hybrid breed. It was domesticated long ago. It is a Scottish breed which has a heavy coat and with short legs. It is used for driving, riding.

> Great Dane is a german breed which is giant in size. It is domesticated. These are gentle, playful, and very good with children and a very good guard.
These are not violent but can be very dangerous and aggressive with the stranger dogs.

> Arabian race horse is Arabian breed and it is the most recognisable horse breed. This breed is one of the oldest breeds. It undergoes selective breeding and it is a quick learner with a good nature and was used in war.

> Peppered Moth is an example of natural selection. It has undergone evolution. The wings are white in color and peppered with black colour. It is also called Darwin’s moth.

> Broccoli is a vegetable which is green in colour and it comes under the cabbage family. It is a result of artificial selection from wild cabbage. Other vegetables include cauliflower, cabbage, etc. Broccoli is invented by humans for a specific taste and flavour.

Hence, The correct answer is option (D).

Note: The process of artificial selection is harmful and not ethical. Artificial selection is much more appealing to humans because of its faster rates than natural selection and also the selection of breeds according to their choice. Artificial selection is also called selective breeding.
